Do you genuinely believe that reading candlesticks will give you insight into the future?

I use to think that but coming up on 1 year of trading now, I'm kind of honestly starting to realize the current candle has little to no weight on what happens next

I've seen so many hammer candles appear before a move down, I've seen so many engulfing candles to be completely demolished in the next move. It just feels like it holds very little actual weight

I see people all the time say "I dont use any indicators just price action and volume" but I don't know how anyone makes that work for daytrading when price action is inherently so unpredictable
